DTC Troubleshooting: P0711 (28)
DTC P0711:
 Problem in ATF Temperature Sensor Circuit
NOTE:
  • Before you troubleshoot, record all freeze data and any on-board snapshot with the HDS, and review General Troubleshooting Information.
  • This code is caused by an electrical circuit problem and cannot be caused by a mechanical problem in the transmission.
  1. Turn the ignition switch to ON (II).
  1. Check the ATF Temp Sensor in the Data List with the HDS.
Does the ATF temperature exceed the ambient air temperature?
YES -
Record the ATF temperature. Leave the engine off for at least 30 minutes, then go to Step 3 .
NO -
Record the ATF temperature. Test the stall speed RPM three times, then go to Step 3 .
  1. Check the ATF Temp Sensor in the Data List with the HDS.
Did the ATF temperature change?
YES -
Leave the engine off for at least 30 minutes, then go to Step 4 .
NO -
Replace the ATF temperature sensor, then go to Step 6 .
  1. Check the ECT Sensor in the Data List with the HDS.
Does the ECT Sensor read about the same as the ambient air temperature?
YES -
Go to Step 5 .
NO -
Leave the engine off until the ECT Sensor reads the same as the ambient air temperature, then go to Step 5 .
  1. Check the ATF Temp Sensor in the Data List with the HDS.
Does the ATF temperature read about the same as ECT Sensor?
YES -
Go to Step 14 .
NO -
Replace the ATF temperature sensor, then go to Step 6 .
  1. Reconnect all connectors.
  1. Turn the ignition switch to ON (II).
  1. Clear the DTC with the HDS.
  1. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
  1. Allow the engine coolant temperature to cool to the ambient air temperature.
  1. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on), and wait for at least 20 seconds, then drive the vehicle at speeds over 31 km/h (19 mph) for at least 5 minutes.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P0711 indicated?
YES -
Check for poor connections or loose terminals between the ATF temperature sensor and the PCM, then go to Step 1 .
NO -
Go to Step 13 .
  1. Monitor the OBD STATUS for P0711 in the DTCs MENU with the HDS.
Does the HDS indicate PASSED?
YES -
Troubleshooting is complete. If any other Temporary DTCs or DTCs were indicated in Step 12 , go to the indicated DTC's troubleshooting.■
NO -
If the HDS indicates FAILED, check for poor connections or loose terminals between the ATF temperature sensor and the PCM, then go to Step 1 . If the HDS indicates NOT COMPLETED, go to Step 9 .
  1. Update the PCM if it does not have the latest software; R20A3 engine model, K24Z3 engine model, or substitute a known-good PCM.
  1. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on).
  1. Allow the engine coolant temperature to cool to the ambient air temperature.
  1. Start the engine, and warm it up to normal operating temperature (the radiator fan comes on), and wait for at least 20 seconds, then drive the vehicle at speeds over 31 km/h (19 mph) for at least 5 minutes.
  1. Check for Temporary DTCs or DTCs with the HDS.
Is DTC P0711 indicated?
YES -
Check for poor connections or loose terminals between the ATF temperature sensor and the PCM. If the PCM was updated, substitute a known-good PCM, then go to Step 15 . If the PCM was substituted, go to Step 1 .
NO -
Go to Step 19 .
  1. Monitor the OBD STATUS for P0711 in the DTCs MENU with the HDS.
Does the HDS indicate PASSED?
YES -
If the PCM was updated, troubleshooting is complete. If the PCM was substituted, replace the original PCM; R20A3 engine model, K24Z3 engine model. If any other Temporary DTCs or DTCs were indicated in Step 18 , go to the indicated DTC's troubleshooting.■
NO -
If the HDS indicates FAILED, check for poor connections or loose terminals between the ATF temperature sensor and the PCM. If the PCM was updated, substitute a known-good PCM, then go to Step 15 . If the PCM was substituted, go to Step 1 . If the HDS indicates NOT COMPLETED, go to Step 15 .
